Anyone help me with this question please ? :)

Write balanced ionic equations for the following:

a) zinc is placed in a copper sulfate solution.
b) lead is added to a solution containing Ag+ ions.
c) iron is placed in a solution containing Na+ and Pb2+ ions.

Zn+Cu2+-->Zn2++Cu

Pb-->Pb2++2e-
Ag++e-->Ag
Pb+2Ag+--->Pb2++2Ag

nothing would happen to the sodium because its more reactive

Fe+Pb2+-->Fe2++Pb

i think this is right
